An adjusting apparatus of a feed opening of a crushing chamber of a crusher includes one or more adjusting parts arranged in connection with the feed opening, which one or more adjusting parts is/are movable during crushing for adjusting a flow area of material which is to be crushed and is flowing through the feed opening to the crushing chamber. The front edges of the adjusting parts form a unitary flow opening, the flow area of which is adjustable by moving one or more adjusting parts. An adjusting system includes the adjusting apparatus for a feed opening of a crushing chamber of a crusher. A method for adjusting a pressing crusher or a crushing plant suitable for mineral material crushing. A method for avoiding a start peak of a crusher. A method for limiting power intake and/or crushing pressure of a crusher.

A wear part for a mineral material processing apparatus includes an outer wear surface which includes an initial phase wear surface to be put in crushing contact with an opposite wear surface, and an end phase wear surface to be taken vertically into use in the crushing process from under the initial wear surface when the wear is progressing. The wear part includes an end phase wear surface with a protrusion to be put in use when the wear of the outer wear surface is progressing. As a result of the wear part including the protrusion working life of the wear part can be prolonged. A mineral material processing apparatus and a mineral material processing plant.

A wear part for a jaw crusher comprises at a first side a wear surface to be directed to a crushing chamber of the crusher; and at an opposite second side a first counter surface which is fixable against a fixed or movable jaw of the crusher in a detach-able manner. The wear part comprises second counter surfaces inclined in opposite directions, for holding the wear part in place vertically and in a centering way in side direction relative to the jaw. A jaw crusher, a mineral material processing plant and a method for fixing a wear part to a jaw of a jaw crusher in a detachable manner. A wedge tightening coming from three directions is locking the wear part in a centering way in place relative to any possible transfer direction.
